The bridge has a large steel casting on each end, whichfits over the auxiliary center plate. These center castingsare spaced 36 ft. from center to center and are joined by agirder made up of two 12-in., channels spaced 19in. apart with the top and bottom cover plates 26 in. wideand ^ in. thick. Under the center portion of the girder isa buffing member which is in line with the underframes ofthe flat cars. The buffer member consists of two 15-in.,33-lb. channels with a bottom cover plate fi in. thick. Ateach end of the channels there is a buffer casting which iscurved to fit the end sills of the flat car. The lower buffermember carries four brackets on each side, which serve assupports for running boards. The bufter member is designedto remove the buffing stresses from the upper girders and thecenter plate, and to insure that the stresses will be trans-mitted to the lower member the } center plates aregiven a
